850ml-1 litre/1½-1¾pts vegetable stock or bouillon
4 tbsp Greek-style yogurt
½ cucumber, halved, deseeded, coarsely grated and squeezed of excess water
a few mint leaves, chopped
Heat the oil in a large saucepan.
Tip in the onions, carrot and peppers.
Cook gently for 15 mins, to soften.
Add the garlic and chilli, and cook for
a few mins more. Pour over the chopped
tomatoes and 800ml of the stock. Bring
to the boil and simmer for 10-15 mins
until the veg is completely tender.
Meanwhile, mix the yogurt, cucumber
and mint in a bowl, and season.

season and spoon into bowls. Serve

on top and a drizzle of olive oil.
